After WW I the U.S. Navy standardized on Lake's flat stern, whose buoyancy kept the propellers and diving planes down in the water.

O-12 224k O-12 (SS-73) was discarded in 1930 to be rebuilt by Lake & Danenhower Inc., of Bridgeport CT., for the Wilkins Artic expedition. Lake had long thought about submarine operations under ice; in 1903, he built a trestle atop his Protector and deliberatley operated her in iced waters. The Nautilus conversion, shown here, was far more sophisticated. Drawing by Jim Christley, text courtesy of U.S. Submarines Through 1945, An Illustrated Design History by Norman Friedman.

O-12 263k (Original Caption) On 4 June 1931, the submarine Nautilus which had been rented from the United States Navy, left Provincetown, Massachusetts, on the first leg of a journey which was destined to take it to within a few hundred miles of the North Pole. Sir Hubert Wilkins, veteran air explorer was in command of this, the first attempt to explore the polar area from a submarine. Although the pole was not reached, Sir Hubert and his scientific staff obtained much data of scientific value. The sub returned to civilization in September after experiencing some hair-raising adventures and escapes from death. In the above picture, the Nautilus is shown amid Polar ice, about to plunge to the bottom of the Polar sea.
